Oh, what a trip down memory lane. I had the Timex 1000. Complete with the memory pack and printer. They were fun. . . fiddling to get the volume control on the tape deck volume just right to play back the recorded programs you had saved. . . after waiting fifteen to twenty minutes to learn it wasn't loud enough. LOL! Still, $199 (IIRC) for a real computer was great!
I think w/o the peripherals the Timex/Sinclair was $100. Had a C64 also, then on to a TRS-80 ( & CoCo3 later) with a speedy 300 baud modem. Those old PCs were great for learning BASIC programming on.
You can get emulators of them that run on Windows, was fun playing a few interactive text games (like “Deadline”) on the C64 emulator. I wasn’t much for the Pacman/DonkeyKong type games.
